<div dir="ltr"><div>Hi Erfan,</div><div><br></div><div>Actually, I could not guess the reason for the error right now, It could be because of your data format, because of the FieldTrip version, or a completely different reason :) I can only suggest trying to define cfg.colormap manually if you haven't done it yet. You can assign a string for colormap. If I am not wrong, the recommended colormaps include 'parula', 'cividis', 'balance',and '*RdBu'. However, you can find more from the link below.</div><div><br></div><div><a href="https://urldefense.com/v3/__https://github.com/fieldtrip/fieldtrip/blob/master/plotting/ft_colormap.m__;!!HJOPV4FYYWzcc1jazlU!7_vQHuRJZ7C2_jEZ-7PdDNKGgdpAwN3zAS8rdYwAGytoJXLC_2TXcxM-7bN5pa86SUEIc9hPnIhO-pXCls4GlpCFBg$">https://github.com/fieldtrip/fieldtrip/blob/master/plotting/ft_colormap.m</a></div><div><br></div><div>I hope it works. <br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, May 9, 2023 at 10:13 PM Erfan Vi via fieldtrip <<a href="mailto:fieldtrip@science.ru.nl">fieldtrip@science.ru.nl</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Elif,<div><br><div>I get the following error while using the ft_databrowse function:</div><div><br></div><div><font color="#ff0000">Undefined function 'ft_colormap' for input arguments of type 'char'.</font></div><div><font color="#ff0000"><br>Error in ft_databrowser (line 686)<br> cfg.colormap = ft_colormap(cfg.colormap);</font><br></div></div><div><font color="#ff0000"><br></font></div><div><font color="#000000">Do you know how to fix it?</font></div><div><font color="#000000"><br></font></div><div><font color="#000000">Thank you for your attention to my problem.</font></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 7, 2023 at 1:48 PM Elif Tülay via fieldtrip <<a href="mailto:fieldtrip@science.ru.nl" target="_blank">fieldtrip@science.ru.nl</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Erfan,</div><div><br></div><div>Maybe I can suggest a way to try until a technical answer comes from Jan.

Hi Erfan,
<div><br>
</div>
<div>These results look like a classical example of a bad channel. If you remove this channel from the data prior to running the IC decomposition, results should look more sensible.</div>
<div><br>
</div>
<div>Good luck,</div>
